and useful Improvements in Check-Row Wire Mechanism for Planters, of which the following is a specification, reference belng had therein to the accompanying drawing.

This invention relates to improvements in check-row planters, that is to say planters in which the seeding apparatus is actuated or controlled by a wire or cord provided with tappets, or devices for moving, relatively, some of the parts of the apparatus as the latter moves across thefield.

The object is to provide an improved wire supporting and guiding mechanism for such planters theprincipal parts of which mechanism can be put together or taken apart with ease and'which dispense with the necessity of loose pins, bolts, or

similar joining or fastening devices, there being in place thereof strong and durable parts for hinging and holding together the movable and the stationary elements that .will withstand blows and shocks.

Figure 1 is a plan view of the front part of a planter having wire guiding mecha nisms embodying my invention. Fig. 2 is a partial side view showing a check-head with one of these mechanisms. Fig. 3 is an end view, some of the parts being shown in section along the line 3 3, Fig. 2, the parts being shown in full lines in the position occupied when they are in a wire retaining position. Fig. 4 is a view similar to that in Fig. 8, except that the parts are shown in the positions occupied when the wire is being discharged. Figs. 5, 6 and 7 are views of detailed parts.

Referring to the drawings '1, 1 indicate the principal parts of the front frame, or the seeder frame, of a planter.

2, 2 indicate the forward projecting parts of the rear, or main, frame, these being pivotally connected to the front frame. At 8, 3 there are seeder mechanisms of any preferred sort, for example those having rotary plates in the bottom of hoppers adapted to receive single kernels and deliver them, one after the other, to the devices which conduct them to the ground. The seeding mechanisms are driven by the rotary shaft 4, which receives power from the main axle (not shown) through gearing and clutch mechanism at 5.

6 is a spring held rock shaft for tripping the driven clutch element and permitting the seeder shaft l to be driven by the gear- T, 7 are forks on the end of the rock shaft 6, adapted to be engaged by the usual tappets on the check row wire.

At each end of the planter there is a wire guiding .mechanism composed of devices upon which the wire can rest as the checkheads move under it, also devices against which it abuts laterally inward, and devices against which it abuts laterally outward. These are carried by a stationary support of suitable character and part of them are held upon an intermediate movable support which is connected to the stationary support. The stationary support is indicated by 9, and is of the nature of a bracket sea cured to the front planter frame.

8, 8 are non-rotary or stationary guides each having a cavity or partially inclosed chamber through which the wire passes.

11 indicates as an entiretya movable support. As shown, it has an axial part and an inwardly projecting part, the former preferably comprising two pintles or trunnions at 12, and the latter comprising plates 11 extending in from the hinge elements to a longitudinal bar part with a vertical flange at 11".

The fixed support has hinge elements which may be apertured'ears or plates such as shown in-Fig. 6. 'The movable support 11 can be connected to or detachably separated from the fixed support by inserting the pintles or trunnions 12 into the companion-hinge elements on the fixed support, provided it be turned to a certain and unusual position. When it is in place and ready for use this movable support 11 is normally in one extreme position, to wit, the wire retaining position, or in another terminal position, to wit, that where the wire is discharged, or is moving from one of these to the other. But provision is made for its being taken to a third, or an unusual, position, and when therein it can be with drawn from the stationary support, and can be reattached, or another can be substituted, as found necessary. For normally holding it in place and preventing endwise move ment there is formed on it a flange 13 which is eccentric in relation to the trunnion 12. The flange normally cooperates witha rib or stop 14: on the fixed support to prevent displacementduring a part ofthe possible path of movement of the part 11; when it reaches another part of said path the flange and rib allow such relative movement as will permit separation. i

With the parts referred to a stop is com.- bined which, under normal circumstances, prevents the movable support from passing through the last said part of its path, that is stops it at the wire discharging place, illustrated in .Fig. 4. If this stop be'made movable the swinging support will he held in permanent engagement with the fixed support under usual circumstances, but, when desired, provision is made for carrying the movable support to the aforesaid third, or unusual, position where attachment or detachment or separation 1s. possible.

0, is a rotary. pulley-like device on the movable. support which serves both as a wire guide element and as: a stop. to limit the nor mal movements of" the swinging sup-port. This pulley or roller is movable, being held in place by a piniengaging. a threaded seat or fastener'in the usual way. There may be two, orv more, of thesepulleys, as desired.

.Asshown, they. are respectively opposite the non-rotary wire. guides 8. When they are.

so positioned thatthey canstrike some part of the'stationary. frame, as. shown in Fig.

4, they pireventthe swinging support from traveling. beyond the, wire discharging: position. But these combined stops and guides 10 be, moved suitably, as by loosening ther; fastening pins, the. swinging frame is allowed to. drop."down to. the aforesaid third, or unusnal,"position where. detachj ment'ispermitted When it is desired: to re- 3. When this position'is reached, the ec centric flange s l3are out of registenwith.

Copies. or this, patent may, be, obtained for the ribs or stops 14 and the entire part 11 can be moved longitudinally in one direction or the other to bring one of the trunnions 12 out of its aperture. Then the disengaged end can be lowered or moved outward and the whole device moved in the opposite direction to release the other trunnion.

As stated above, the guide pulleys 10 normally act as stops for limiting the downward swing of the pivoted element 11, but these stops can be removed, When desired, to permit the detachment of the said part.

At 15 there is a spring latch for holding the swinging part locked in position when the machine is in operation and the wire is passing through the guide-way. This latch is opened by the driver when he reaches the end of a row by means of the rod 16 and the pedal at 17. When he exerts pressure on the pedal the latch is opened and the strain of the wire pressing laterally outward against the movable guides throws the swinging support to the position shown in Fig. 4 and the wire is discharged upon the ground.

What I claim is:

In a wire guiding mechanism for a checkrow corn'planter, the combination of two elements, the first of which is stationary and the'second of which is movable from a wire retaining position to a wire discharging positionand also. to a third unusual position, guide. rollers on the movable element adapted to limit the movement thereof to the said third position by direct engagcment with the said stationary element, the said movable element being held permanently in engagement with the fixed: element while in the first two positions but being bodily detachable from said support when inthe third position.

In testimony whereof, I afiix my signa ture, in presence of two witnesses.
